The Distance to Overtake calculator computes the distance required to overtake a vehicle based on the speeds of the two vehicles and the head start.

INSTRUCTION: Choose units and enter the following:

• (h)  Distance between the vehicle (i.e. the head start)
• (V₁) Velocity of Chase Vehicle.
• (V₂) Velocity of Lead Vehicle.

Distance to Overtake (d): The calculator returns the distance in miles.  However, this can be automatically converted to compatible units via the pull-down menu.

• Time to Overtake: Computes the distance in which the overtake will occur at constant velocities.
• Distance to Overtake: Computes the distance in which the overtake will occur at constant velocities.
• Speed to Overtake by a Distance: Computes the speed required to intercept within a distance boundary.
• Speed to Overtake in Time: Computes the speed required to intercept within a time boundary.

The Math / Science

The formula for the time required to overtake is:

        d = V₁•h / (V₁ - V₂)

where:

• d is the distance required at the specified velocities for vehicle 1 to overtake vehicle 2.
• h is the distance between the vehicles or the head-start.
• V₁ is the velocity of vehicle one
• V₂ is the velocity of vehicle two.
